Taking cue from iris scans used in UID in India, researchers are developing a new biometric system that can identify people by the way they flicker their eyes while looking at a computer screen.
Oleg Komogortsev, a computer scientist at Texas State University-San Marco, is making use of the fact that no two people look at the world in the same way. When looking at a picture, different people will move their eyes among points of interest in different sequences, researchers observed.
Even if two people trace the same paths, the exact way they move their eyes differs, the ‘LiveScience’ reported. “We are seeing there are enough differences so we can talk about this as a biometric,” Komogortsev told TechNewsDaily.
A biometric is a measurement of something on the body – fingerprints, for instance – used to identify people. Computer scientists all over the world are studying biometrics for crime solving, for border security, and just as a high-tech way to sign into smartphones, tablets and other devices.
